Nickel Ore an overview ScienceDirect Topics
Because the ores processed vary widely in terms of nickel content and other components, it is natural that both lower and higher reduction degrees are used. Low reductions imply higher slag losses and lower nickel recoveries but also lower power and reductant requirements, whereas higher reductions imply the reverse (Solar et al., 2008). In some cases, nickel scrap and remelts are added to low-grade

Nickel: smelting, producing-Metalpedia
Nickel: smelting; Extraction and purification; Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of the impurities.
